When it comes to management, one of the things I ask customers is what management tools they use. There's always a laundry list, some open-source (like Nagios) and some from large software vendors (like Tivoli). These IT management tools are used to get a handle on computing, storage, networking, and applications -- 4 of the primary assets in a data center. But when I ask what they use for energy management, there's usually a blank stare. Energy, as you may have guessed, is the fifth major asset. As with any of these assets, if you run out of capacity, your applications go down. If you don't manage them proactively, your performance suffers. Energy is no different. And with pressure to reduce cost, improve performance, plan for increased or decreased capacity, or mitigate potential risks, management tools are the key to accomplishing these tasks.
Awareness of the importance of energy in the data center has grown dramatically in the last few years. And due to the importance of energy in business continutity and contribution to data center operating costs, it is logical that it is time to get a handle on energy in 2010.
